Just Star Battle

Just Star Battle is a quiet take on Star Battle. The board is divided into regions of irregular shapes. Place exactly the required number of stars in each row, each column, and each region — with one extra rule: no two stars may sit in neighboring cells, including diagonally.

Three small rules govern the whole game:

1. Tap a cell to cycle empty → × → star. The × is a player annotation for "definitely not a star"; only stars affect the solution.
2. Place exactly k stars in every row, every column, and every region.
3. No two stars may touch — including diagonally.

Simple rules, plenty of room to think.


CONTENT

— Over 1500 hand-curated puzzles, every one verified to have a unique solution.
— Two phases of play. First, work through the campaign — a steady curve from gentle 5×5 starters up to dense 14×14 / 3-stars-per-region boards. Then Free Play opens: pick any difficulty and keep drawing from the library at your own pace.


PART OF JUST PLAY

Just Star Battle is the sixth game in the Just Play series, after Just Sudoku, Just Puzzle, Just Yin Yang, Just Stack, and Just Hanoi. The series shares one design philosophy: classic logic puzzles, patiently rebuilt, in a quiet voice. No ads, no streaks, no engagement loops. The interface stays out of the way; the puzzle does the talking.


PLAY YOUR WAY

— Tap to cycle through the three cell states. No drag, no long-press.
— Restart any level at any time — never costs you anything.
— Region tints help your eye partition the board on the larger grids.
— Soft haptics that confirm your touch without shouting.
